"just like in every other restaurant on the planet" You mean just like every restaurant in USA. I rarely tip in France, only if I had a really special interaction with the waiter/waitress. Once it was because the waitress was a student we chit chat a bit and ended up talking programming (!). I never tipped once in China (nobody does it there)
